So lots of lag and funky quest shenanigans after the rollover, and I didn't think too much about it at the time. Most of them were nbd and more funny than anything (like the Wizard not giving me the fifth Shinwa piece I needed and then Shinwa asking for another 5th piece after I already turned it in to her) but I just did Saggitarius' quest and lost a decent chunk, so now I'm afraid to try another quest.
I spent roughly 120k (I unfortunately didn't think to ss the items or the exact amount of sP I had on hand before this, because I didn't think this would happen), but I did go back and screenshot the result after I noticed my amount on hand did not go back up after the quest.
I started with about.. 280k I think? so the amount I'm left with is incorrect before all else, and completing the quest for the reward I should've gotten 234,236 sp back on top of the proper remainder, which means I should be sitting at like 394k or so (give or take a couple thou since I can't recall the exact starting amount nor the exact amount of what I spent).
I mean, it's not a lot of sP in the long run so nbd there, either, I'll cut my losses.
I just figured a heads up on the wonky calculations and a lack of reward being... er... rewarded would be a good idea? And I wasn't certain if putting in a ticket was what I should do, or if just posting in the bug forum was all that was necessary to give a heads up.
E2A: Oh yeah, and several other quests today for both me and my roommate and a couple other folks in the shoutbox were acting like items purchased for turn in weren't there, plus lag seemed to mean ending up with multiple copies of an item purchased. I don't know if they were duplicated or actually purchased, but.. Offhand, I remember it being for the Librarian as the culprit in this case, but not what books were asked for. (They weren't expensive, either, on my end--just a couple thousand sP I think for mine? IDK.)
Anyway, yeah. Lots of weirdness with the quests this morning and I should've left well enough alone until I heard that stopped. :(

I'm having trouble too. I did several Wizard quests, only to realise that I never got the sP from it. I did get the tokens, however.
I had it, too, and was also thinking if it would be necessary for making a ticket about this ? I had first problems with Pete (posted in the news, too) because quest was stating I wouldn´t have all the items asked for and when buying again and trying to finish the quest a second time, the reward was not given sometimes and the quest clicked back to the quest start site. Shinwa don´t let me finish the quest yet when I looked, the item she had apparently given to me for finishing her quest was in my inventory. I´ve done the Wizard and got only very few SP yet all of the tokens. Then I started Saggitarius full of hope and here it was really bad: For the first quest, I bought Plum Summery Dress 76998 SP Kirin 41999 SP Antique Ashen Arm Chair 29637 SP The SP was deducted from my offhand SP and an reward was shown about 267000 SP yet not given to my total SP. I started a second quest for a test and had White Zebra Knee Highs 732 SP Black Flower Barrette 3975 SP Reward 78000 SP, not given again. I stopped playing here because it would be sad loosing all the money with Saggi of all things because he mostly gives nice rewards. I am apprehensive now doing another quest. That´s a pitty because due to my working times, I am not able to go online this night for a long time doing quests, my questing time is now.

I haven't noticed any other glitches yet, but Pete isn't giving out the bracelet piece I need for Shinwa...
Yeah, I didn't seem to make much, if any, profit from Pete's or Quentin's, the two sets I managed before things went totally haywire. Felt like I should have because I was seeing reasonable sP rewards, but my actual sP didn't seem to be going up very much. I'm not too fussed, but I don't want to finish today's quests until I know they're fixed--esp not Saggi!
And, like Sunflower mentioned, there were weird issues around rollover with the lag. The site choked whenever I tried to buy something from the main shops, so I suddenly got two or three of the item. As far as I know, it took my sP for each item, so I don't know that it was duping. Probably just the site going ahead with purchasing the items even if all I was getting were downtime errors.
Library gave me trouble around 12:30-12:50 or so. Either it would tell me I didn't have the necessary items or it would tell me I wasn't on a quest. I'm really not sure if I managed to get anything out of the Library at all, since I almost never saw the reward page but my number of completed quests crept steadily up. I'm at 16/15 completed, despite not having a buff for that. I assume attempting to reload the quest page after getting a "subeta is down" message may have messed with it a bit.
Vesnali sure is starting things off like a lion. Hopefully it finishes like a lamb.
